Romero-Garcia , Gonzalo | 2021-11-05

This manuscript presents an integral evaluation of the use of wind and solar resources in the Colombian Caribbean region. For the use of solar and wind energy sources, spatial restrictions according to topography, natural parks, water reserves, indigenous and sacred reserves were taken into account. In addition, studies of the energy potential of wind and solar radiation were carried out through geostatistical analysis of different points in meteorological stations located in the region. Finally, areas with wind and solar potential were determined using the Geographic Information System for Renewable Energies (SIGER). The results show that the department of Guajira has the highest values of solar brightness (229-240 Month day), while the departments of Valledupar, Cesar, and part of Magdalena decrease in the range of 229 to 207 Month day. In terms of solar radiation, the departments of Guajira and Atlántico showed global solar radiation values of up to 6,015 W/m2. The departments of Cesar, Magdalena, and part of Bolivar showed values close to 5,259 W/m2; while Sucre, and Cordoba showed low solar radiation values of 4,502 W/m2. It is concluded that the departments of Atlántico and Guajira are excellent candidates for solar and wind energy projects due to their characteristics. The results of this manuscript are a fundamental basis for future technical-economic feasibility studies of renewable energy in the Colombian Caribbean region. In addition, it allows the elaboration of energy policies that encourage the execution of this type of study at a real level.

The fabrication lightweight aggregates in recent years has included the addition of industrial by-products in the expanded clay manufacture as modifier agents of the expansion capacity, and also as a destination for the disposal of waste and residues in countries where lightweight concrete is used for the construction of high-rise structures. This article provides a review of the use of by-products as additives in the production of lightweight aggregates from expanded clay available in the literature. As a methodology, the bibliographic search was used through the consultation of specialized databases such as Sciencedirect and other documentary sources of open access scientific journals in several countries. The selection criteria for documents were specified according to the frequency the by-product use. 58 references on investigations by-products addition to the lightweight aggregates production were revised. In conclusion, the study of the use of Colombian byproducts as additives in the expanded clay aggregates production is suggested as a research subject due to the absence of articles related to this topic.

The design and operation of sanitary sewerage systems are based on the knowledge of peak and the average daily wastewater flows. The maximum peak factor is obtained through the ratio of the maximum flow and the average discharge flow of wastewater generated in a system. In this sense, the maximum peak factor was estimated by monitoring wastewater flow in an urban sector of the city of San José de Cúcuta, Colombia. This urban sector represents 45.6% of the sanitary sewerage of the city. Stochastic modeling of the peak flow was performed, and a mathematical model was constructed to estimate the maximum peak factor using a correlational study using statistical methodology. Through linear regression analysis, a model was obtained that estimates the value of the maximum peaking factor based on knowledge of the average daily wastewater flow. The results indicate that the model is potential, and the expression is statistically significant and satisfies the assumptions established for the classical linear regression model.

The increase in distractions when driving or walking on a road has proportionally increased the number of accidents that occur each year, with pedestrians being the most affected. For this reason, an attempt is made to study the characteristics of a vehicle road, identifying the critical points and road sections of maximum demand of the inhabitants, who are the ones most in need of pedestrian crossings. For this reason, a statistical and technical study of traffic is proposed by means of vehicular gauges with respect to the most representative days that help to determine quantitatively the vehicular flow that circulates through this road corridor, by means of graphs, tables that help to identify the statistical data without still leaving aside the importance of a study of pedestrian traffic by means of a count in typical days of mobilization with the purpose of determining the pedestrian volume, due to its increase in the indexes of accidents caused by different types of transport, in which the motorcycles stand out.

Public transport is one of the major means of mobilization for the general population of a country, achieving great importance to its policies of mobilization and economic analysis because it creates controversy to have a poor quality of service, directly affecting the users and drivers of these means. Due to the above, an alternative is proposed for the decongestion of main public transport routes, presenting the degree of saturation and the performance index that can create different alternative routes by moving a percentage of the routes in the city of Cúcuta, Colombia. In order to evaluate the effectiveness of this solution, information was collected by means of surveys for users and drivers, analyzing the data with the SPSS version 21 software, manifesting that there is low quality in public transport. In this way, the final characteristics of this method are evaluated in the new alternatives and in the problem sector, satisfying the quality requirements of public transport worldwide.
